which want to include namespace support.</p>
<p>You can set the prefix for the current namespace with <a href="qxmlnamespacesupport.html#setPrefix">setPrefix</a>(), and get the
list of current prefixes (or those for a given URI) with <a href="qxmlnamespacesupport.html#prefixes">prefixes</a>(). The namespace
URI is available from <a href="qxmlnamespacesupport.html#uri">uri</a>(). Use <a href="qxmlnamespacesupport.html#pushContext">pushContext</a>() to start
a new namespace context, and <a href="qxmlnamespacesupport.html#popContext">popContext</a>() to return
to the previous namespace context. Use <a href="qxmlnamespacesupport.html#splitName">splitName</a>() or <a href="qxmlnamespacesupport.html#processName">processName</a>() to split
a name into its prefix and local name.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QXmlNamespaceSupport" />QXmlNamespaceSupport.__init__ (<i>self</i>)</h3><p>Constructs a <a href="qxmlnamespacesupport.html">QXmlNamespaceSupport</a>.</p>


<h3 class="fn"><a name="popContext" />QXmlNamespaceSupport.popContext (<i>self</i>)</h3><p>Reverts to the previous namespace context.</p>
<p>Normally, you should pop the context at the end of each XML
element. After popping the context, all namespace prefix mappings
that were previously in force are restored.</p>
<p><b>See also</b> <a href="qxmlnamespacesupport.html#pushContext">pushContext</a>().</p>


<h3 class="fn"><a name="prefix" />QString QXmlNamespaceSupport.prefix (<i>self</i>, QString)</h3><p>Returns one of the prefixes mapped to the namespace URI
<i>uri</i>.</p>
<p>If more than one prefix is currently mapped to the same URI,
this function makes an arbitrary selection; if you want all of the
prefixes, use <a href="qxmlnamespacesupport.html#prefixes">prefixes</a>() instead.</p>
<p>Note: to check for a default prefix, use the <a href="qxmlnamespacesupport.html#uri">uri</a>() function with an argument
of "".</p>
<p><b>See also</b> <a href="qxmlnamespacesupport.html#setPrefix">setPrefix</a>().</p>


<h3 class="fn"><a name="prefixes" />QStringList QXmlNamespaceSupport.prefixes (<i>self</i>)</h3><p>Returns a list of all the prefixes currently declared.</p>
<p>If there is a default prefix, this function does not return it
in the list; check for the default prefix using <a href="qxmlnamespacesupport.html#uri">uri</a>() with an argument of
"".</p>


<h3 class="fn"><a name="prefixes-2" />QStringList QXmlNamespaceSupport.prefixes (<i>self</i>, QString)</h3><p>This is an overloaded function.</p>
<p>Returns a list of all prefixes currently declared for the
namespace URI <i>uri</i>.</p>
<p>The "xml:" prefix is included. If you only want one prefix that
is mapped to the namespace URI, and you don't care which one you
get, use the <a href="qxmlnamespacesupport.html#prefix">prefix</a>() function
instead.</p>
<p>Note: The empty (default) prefix is never included in this list;
to check for the presence of a default namespace, call <a href="qxmlnamespacesupport.html#uri">uri</a>() with "" as the
argument.</p>


<h3 class="fn"><a name="processName" />QXmlNamespaceSupport.processName (<i>self</i>, QString, bool, QString, QString)</h3><p>Processes a raw XML 1.0 name in the current context by removing
the prefix and looking it up among the prefixes currently
declared.</p>
<p><i>qname</i> is the raw XML 1.0 name to be processed.
<i>isAttribute</i> is true if the name is an attribute name.</p>
<p>This function stores the namespace URI in <i>nsuri</i> (which
will be set to an empty string if the raw name has an undeclared
prefix), and stores the local name (without prefix) in
<i>localname</i> (which will be set to an empty string if no
namespace is in use).</p>
<p>Note that attribute names are processed differently than element
names: an unprefixed element name gets the default namespace (if
any), while an unprefixed attribute name does not.</p>


<h3 class="fn"><a name="pushContext" />QXmlNamespaceSupport.pushContext (<i>self</i>)</h3><p>Starts a new namespace context.</p>
<p>Normally, you should push a new context at the beginning of each
XML element: the new context automatically inherits the
declarations of its parent context, and it also keeps track of
which declarations were made within this context.</p>
<p><b>See also</b> <a href="qxmlnamespacesupport.html#popContext">popContext</a>().</p>


<h3 class="fn"><a name="reset" />QXmlNamespaceSupport.reset (<i>self</i>)</h3><p>Resets this namespace support object ready for reuse.</p>


<h3 class="fn"><a name="setPrefix" />QXmlNamespaceSupport.setPrefix (<i>self</i>, QString, QString)</h3><p>This function declares a prefix <i>pre</i> in the current
namespace context to be the namespace URI <i>uri</i>. The prefix
remains in force until this context is popped, unless it is
shadowed in a descendant context.</p>
<p>Note that there is an asymmetry in this library. <a href="qxmlnamespacesupport.html#prefix">prefix</a>() does not return the
default "" prefix, even if you have declared one; to check for a
default prefix, you must look it up explicitly using <a href="qxmlnamespacesupport.html#uri">uri</a>(). This asymmetry exists to
make it easier to look up prefixes for attribute names, where the
default prefix is not allowed.</p>
<p><b>See also</b> <a href="qxmlnamespacesupport.html#prefix">prefix</a>().</p>


<h3 class="fn"><a name="splitName" />QXmlNamespaceSupport.splitName (<i>self</i>, QString, QString, QString)</h3><p>Splits the name <i>qname</i> at the ':' and returns the prefix
in <i>prefix</i> and the local name in <i>localname</i>.</p>
<p><b>See also</b> <a href="qxmlnamespacesupport.html#processName">processName</a>().</p>


<h3 class="fn"><a name="uri" />QString QXmlNamespaceSupport.uri (<i>self</i>, QString)</h3><p>Looks up the prefix <i>prefix</i> in the current context and
returns the currently-mapped namespace URI. Use the empty string
("") for the default namespace.</p>
